IMPROVEMENT lN SPRlNG BED-BOTTOMS.

Specification forming part of Letters Patent No. 130,788, dated August 27,1872.

SPECIFICATION.

To all whom it may concern:

Be it known that I, SILAs M. BROOKS, of Burlington, in the county of Hartford, and in the State of Connecticut, have invented certain new and useful Improvements in Spring Bed-Bottoms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in constructing a spring bed-bottom, with an independent central transverse slat provided with I a series of double circular springs, which slat,

as well as the longitudinal slats on which the bed rests, has its series of springs secured to a frame formed of three cross-pieces the width of the bed, and two longitudinal bars, as will more fully hereinafter appear.

To enable others skilled in the arts to make and use my invention I will now proceed to more specifically describe its construction.

In the drawing, Figure l is a side elevation of my bed-bottom, and Fig. 2 is a detail view representing one o'fthe double circular springs secured to the independent transverse slat.

A is one of two longitudinal'bars, forming with the cross-pieces B B B, which are as long as the bed is wide, the frame of the bed-bottom. C represents one of the several longitudinal slats on which the bed is placed all of these slats are of the same size and as long as the bed, and each is secured to a couple of circular springs, D, that are firmly fastened to the end cross-pieces B. (See Fig. 1.) The independent center slat E is secured to a series of double circular springs, F, that are screwed securely to the center cross-piece B and slat E is as long as the width of the bed, and extends below the slats C. The double circular spring F is composed of a large circular spring and a small circular spring, f, firmly secured to the center cross-piece B. The spring f is provided with a pad, 6, made of rubber or other suitable material, and the bly use them with the center slat E, because. the occupant of the bed more frequently puts a violent and sudden strain upon the springs near the center of the bed, by sitting on them,

&c., than on any other of the springs, and the double spring from its greater strength is not so liable to break or become set. The pad 0 prevents the noise that would result from the sudden clash of the springs if the pad were not provided. This double spring F can be readily adapted to sofas, lounges, chairs, and other similar purposes.

As my bed-bottom is made of straight pieces of wood and plain bands of steel of one coil secured together by screws, I can furnish a remarkably cheap and good spring bed-bottom. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of the independent transverse slat E provided with a series of double springs F, with the frame A B B B, slats C and springs D, when constructed and operating substantially in the manner, and for the purpose specified.

2. The combination of the inner circular spring f provided with a pad, 0, and the outer circular spring F, as a bed-bottom or other spring, constructed and operating substantially in the manner and for the purpose set forth.

In testimony that I claim the above-described certain new and useful improvements in spring bed-bottoms, I have hereunto signed my name this 19th day of December, 1871.
